are based on a 2.0 safety factor times the sum of working pressure and 100 psi surge allowance. (See ANSI/AWWA C150/A21.50 for design
formulas.) Ductile iron pipe for working pressures higher than 350 psi is available.

FIG. 1 GASKET INSERTION
The inside of sockets and the outside of spigots should be cleaned up to the insertion
depth. Gaskets should be wiped clean and inspected for damage. The gasket should then
be placed into the socket groove, rounded end entering first. Seating the gasket is made
easier by forming the gasket into a loop during insertion. The heel of the gasket should
fit uniformly into the retainer seat. On pipes larger than 12”, additional loops may help in
placing the gasket in the seating.
PIPE ASSEMBLY
FIG. 2 LUBRICATION
Ensure that the spigot end is properly chamfered or rounded to avoid tearing of the
gasket. Clean away all foreign matters from contact area of pipe. Apply a thin film of
recommended lubricant to the mating surface of the gasket. Avoid spray-on lubricants
as these may not provide enough lubrication. Avoid petroleum based lubricant as it may
damage the gaskets. Once lubricated, do not let lubricated area touch the ground or
other contaminant, compromised seal could result.
FIG. 3 PIPE AND FITTING AND ASSEMBLY
Spigot should be inserted in socket. If socket is pushed, the gasket may be displaced.
Align and center the spigot in the socket and keep it in this position. Now gently push the
spigot into the socket by suitable mechanical means, maintaining the alignment and level.
A suitable gap should be left between the spigot end and the bottom of the socket to
take care of any axial movement, deflection or temperature variation. To ensure this, two
band marks are made near the spigot end. These bands act as a ‘Go’ and ‘No-Go’ gauge.
After jointing, the end of the socket must end between these two bands. If moderate force
does not result in a solid seal, remove the pipe and inspect for foreign matters, improper
lubrication or misaligned gasket. Once you are certain of a solid seal, joint deflection can be
applied within the permissible limits.
FIG. 4 INSPECTION OF JOINT
Verification of the gasket’s position is easily accomplished with a feeler gauge. Insert the
gauge into the joint until it touches the gasket. Check the gasket position all around the
joint, making note of the depth required to contact the gasket. Any changes in depth
indicate the gasket has slipped out of place. If this is the case, disassemble joint and clean
all pipe contact areas and gasket. Once inspected for the fault, reassemble using the
guidelines above.

fig. 4
PREPARING A FIELD-CUT PIPE
Pipe that has been cut on site can easily be made ready for use by giving the plain end a
bevel. With a portable grinder, create a 16° angle around the outside edge of the cut end.
The edge of bevel and plain end of the pipe should be rounded off with the grinder.
Grinding should produce a bevel that continues back about 1” from the edge. This bevel
will ease assembly and protect the gasket from damage by removing rough edges.
Special consideration should be given to cutting pipe 14” or larger. In this case, pipe should
be gauged full length.* Pipe that is gauged full length will be marked as such and conforms to
ANSI/AWWA C151 Standard for Ductile Iron Pipe requiring spigot end factory gauging.
To ensure tolerances, pipe for field cutting needs field gauging at the point of where the cut is
to be made. Mechanical joint glands can be used for field gauging.
* NOTE A full length gauged pipe is a pipe whose outside diameter is within the spigot
diameter specifications. Full gauged pipes should be specially ordered.
ALTERNATE METHODS FOR ASSEMBLY
ASSEMBLY WITH A BACKHOE (for a l l DN)
Taking a few precautions, it is possible to use the hydraulic force of the arm
of a mechanical digger to assemble pipes and straight fittings. In this case:
n Place a wooden batten between the pipe and digger bucket
n Exert a slow and steady force observing the rules for joint assembly
n A timber block should be placed between the bucket and the pipe
to avoid damage of the socket.
Electrosteel USA recommends following the procedures outlined in the
previous section before attempting the alternatives listed below.
ASSEMBLY USING A CROWBAR
For smaller sizes (for 3” to 6” dia.) a crowbar may be used for
assembly. This method involves using a crowbar as a lever and
pushing against the face of the bell. The pipe socket face must be
protected with a piece of hard wood.
